If you are upgrading from a significantly older version of Communicator (HC 2018 U2 and older), the permissions issue could be due to the switch from .zip archiving to .tar. More specifically, .zip was used to archive packages from HC 2018 Update 2, inclusive, and earlier. After which, .tar was then used. In essence, extracting the zip was causing different file ownership compared to .tar.
The solution is to add --no-same-owner to the .tar command, for example:
sudo tar xzf HOOPS_Communicator_2022_Linux.tar.gz --no-same-owner
